    Abstract: An expandable tool includes a body and a recess extending at least partially through the body from an outer radial surface of the body. A spline insert may be at least partially positioned in the recess and coupled to the body. The spline insert may include a single spline or multiple splines. A cutter block or other expandable member may be at least partially positioned in the recess. The cutter block or other expandable member may include a spline on a side surface thereof, which spline may be engaged with the one or more splines of the spline insert. Engagement between one or more splines of the spline insert and spline of the cutter block or other expandable member may allow the expandable member to move radially outward from a retracted position to an expanded position, and vice versa.

    Abstract: A cutting tool (1) for widening the diameter of a borehole and method thereof is disclosed. The cutting tool (1) comprises a housing (2) having cavity (10) in which a moveable activation element (6) is arranged. The activation element (6) is moved in an axial direction and is connected to one or more cutting blocks via a mechanical coupling (15). The mechanical coupling (15) transfers the axial movement of the action element into a radial movement of the cutting blocks. An activation unit (24) pushes the activation element (6) towards a stopping position which in turn causes the cutting blocks (11) to move out of the housing. The activation unit (24) further pulls the activation element back towards its starting position which in turn causes the cutting blocks to move back into the housing. The cutting blocks (11) extend into one or more cavities formed in the activation element, thereby increasing the travel-to-expansion ratio. The cutting blocks can be replaced by stabiliser blades (20) which are used to stabilise the drilling in the expanded borehole.

    Abstract translation: 公开了一种用于加宽钻孔直径的切削工具(1)及其方法。 切割工具(1)包括具有空腔(10)的壳体(2),可移动的激活元件(6)布置在该壳体中。 激活元件(6)沿轴向移动并且经由机械联接(15)连接到一个或多个切割块。 机械联轴器(15)将动作元件的轴向运动传递到切割块的径向运动。 激活单元(24)将致动元件(6)推向停止位置,该停止位置又导致切割块(11)移出壳体。 激活单元(24)进一步将激活元件拉回其起始位置,这又使得切割块移回壳体。 切割块(11)延伸到形成在激活元件中的一个或多个空腔中,从而增加行程与膨胀比。 切割块可以由用于稳定在扩大钻孔中的钻孔的稳定器叶片(20)代替。
